Spectrum Analyzer

[Steve Warson]

Hi from Spain.

Well, I wonder if someone on this group can give me a hand. I would like
to install on my computer a spectrum analizer to actually see the
frequency range on my mp3s. I am running XP.

Any suggestion from the group?

Many thanks in advance for your cooperation.

FELIZ NAVIDAD!!!!

Regrettably, everything I use is pretty expensive for just random fooling
around:

Depending on how technical you need to get, it's built in to Media Player.

TrueRTA is excellent and free in its basic version. For Mac OSX,
SignalScope, from www.benjaminfaber.com is excellent, and cheap.

The frequency range will actually depend on the *source* i.e. the original
recording - NOT your pc - or the algorithm used ( mostly ) or whatever.

If you want to see *bouncing lights* there's plenty of audio players out
there that do it. I think winamp has an option to display this IIRC. Usually
when a 'spectrum analyser' option is available you can also view the
waveform too. It's almost entirely useless apart from an entertainment
aspect though.

IIRC CoolEdit would do that, and I believe that is what I was using
when I found that FhG in the MusicMatch Jukebox codec (circa 2000) had
a cutoff at 16KHz and so switched to Media Center with LAME which
cutoff around 21KHz.

I see. However, thanks for your input.

I know, but in Media Player I do not have the faintest clue of wich are
the frequencies actually shown. Regretably, does not help. Thanks anyway.

Is not really to see the lights. What I am trying is to see in a mp3
encoded at 256 kbps that it has been ORIGINALLY encoded at that speed.
My impression is that there are plenty of re-encoded songs that had been
encoded, let's say, at 64 kbps and lately re-encoded at 256. I would
like to have a tool to see where the frequencies are actually cut-off to
have an idea about the actual encoding speed. Hope is clear keeping in
mind that my english is limited :-(

Thanks Graham

I am afraid you are wright, and this takes us to Arny Krueger reply :-(

**That would depend, to a large extent, on the type/s of drugs being used.

I doubt that a tool as limited as a spectrum analyser will be able to do this
meaningfully.

MP3 encoding uses more tricks than limiting HF content. 64kbits/sec is pretty
hopeless for music whatever.

Orville, of course.
